This issue occurs because of an error in the Atapi.sys file. Before Windows Vista enters hibernation, Windows Vista has to write the memory to the hibernation file on the disk. However, in some cases, the storage drive may not return the correct value when system tries to initialize the corresponding storage stack. When the storage drive returns an incorrect value, Windows Vista stops responding.
